Contrast checks with fixes, OKLCH harmonies, palettes, color-blind previews and code export.
Scored across 6 tools
Each tool has a clearly distinct purpose: color-space conversion, contrast checking, code export, harmony generation, constrained palette rolling, and vision-deficiency simulation. The two palette-generation tools are differentiated by deterministic base-color harmony versus random/locked palette generation.
All six tools follow a consistent snake_case verb_noun pattern: check_contrast, convert_color, export_palette, generate_harmony, roll_palette, simulate_color_vision. The naming is predictable and immediately readable.
Six tools is well-scoped for a focused color utility server. Each tool covers a distinct capability without obvious redundancy or bloat.
The surface covers core color workflows: conversion, contrast checking, palette generation, harmony generation, export, and vision simulation. Minor gaps such as palette save/load or image-based color extraction exist, but agents can work around them for typical color tasks.
Check text/background contrast with WCAG 2 ratio, APCA Lc and a suggested fix that keeps the hue.
